Richard Dwyer1880nonsports brought up something that hasn't been discussed yet on this pack. The glassine envelope. All my Piedmont packs dated 1909-1911 had Tin Foil, and not a glassine envelope.
I was shocked to find out that many non sports cards could have been inserted into 1910-1911 T206 brand boxes. I'm currently making a list of all possibilities and will post that info when done.
